I'm giving a thumbs up to Sam's advice. I'll add a couple of thoughts to the mix;
5x5 on the bigger lifts is good advice. This of course builds strength and size. On your program example, you have squats on both workouts, no problem there. On either your A or B workout you could add a lift after the 5x5 that is in the hypertrophy rep range. For example, do the 5x5 for squats and then at the end add in something like a leg extension or sissy squat or a lunge. Just for a set or two and perhaps for 12 reps. This will of course get the blood flowing in the legs which is a good thing. It is getting you used to some additional work but not overwhelming you.
You can add shrugs on one workout and calves on the other. I'll differ with Sam on one point on the calves, they can respond very well to very high rep ranges. With a one-leg DB calf raise I will go for 15 or more reps and on a donkey calf raise I like to reach 100 with BW in 2-3 sets (100 total).
Curls are fine, I would suggest doing a straight curl on one workout and a hammer curl on the next. You won't need more than 2 or 3 sets. The bicep isn't a large muscle and you're already getting some bicep work with rows and chins. And personally I like to do reverse curls with an EZ bar, worth throwing into the mix as well, but not at the same time as the other curling lifts.
On the DL, the SL program recommends only 1x5. You may want to stick with that. I don't do DL's at all, that's just me.
Main point, regardless of what rep or exercise you're using, each and every rep is a single event. Make THAT rep the very best rep you've ever done, then follow it with the next very best rep and so forth.
I think you've got a good program forming

Body building isn't everything...it's just that being small, weak and puny really sucks.
